With social media updates and conference agendas addressing the subjects of climate change, emissions reductions and alternative fuels, it’s a wonder we are not climbing the Himalayans in search of the Jedi Master that will provide us with the magic potion. Yoda’s blessing with a calming breath, “You have chosen wisely.”Government emissions intervention started with a move to reduce energy and fuel consumption measured in greenhouse gas (GHG), at a time when the world and our politicians spoke about global warming.

Ship owners increasingly face complex investment decisions as they try to navigate the most efficient course to the low-carbon future. Ever since the IMO set the industry’s ambitious emission-reduction targets for 2030 and 2050, owners have been inundated with information about future fuels and technologies that may, or may not, ultimately lower the carbon footprints of their fleet.Some of the new technologies hold promise, but the day-to-day viability of too many of them remains unproven; the same can be said for many of the potential fuels.

Navigating the Rough Waters of Marine Certification

The marine industry brings its own unique set of challenges.With the ‘All Subsea Factory’ market trend moving offshore exploration and production equipment for oil and gas to the seabed, safety, longevity and environmental protection are just a few of the considerations when choosing marine products. When selecting products for marine applications, the understanding of factors such as marine certifications and inspection documents are crucial to making an informed decision.Worldwide statutory provisions enacted by the United Nations (UN) agency on shipping specify general regulation and rules necessary to obtain an operating license for all categories of ship, marine and offshore applications.
